I would argue in favor of keeping only the "greatest common divider".
The distinction between Item and Manifestation seems quite stable. Seems
to me that they correspond to the notions of Entity and Resource in the
Web (HTTP) terminology.
Besides that, I would be tempted to say that a Resource can be "derived
from" another Resource, and that this relation subsumes the
Manifestation-Expression, Expression-Work, Work-Work relations in FRBR,
or the Broadcast-Version, Version-Episode relations in the BBC ontology.
